Hi, I want to configure ether2 to be disable on certain days and hours, only wirelss to work. I tried in firewall, schedule works, but I have: in / out interface matcher not possible whwn interface (ether2) is slave-use master instead (bridge). I tried that too, but I don't have internet or wifi anymore.

You can disable certain bridge port using command
... or disabled=no to enable it again. Use that in a scheduled script ...

This completely disables bridge port, also for LAN traffic. If you want to disable only internet access for devices connected to that port ... then that's a bigger problem ... unless you know (LAN) IP addresses of those devices in which case you block access based on src-address ...

Thanks for the answer, I tried ether2 = bridge but it still doesn't accept firewall rule. Maybe you need another bridge and vlan. Yes, I don't know ip from lan and mac, it was easy to block, you need everything there to not work.
